Abstract
A base body includes a first part and a second part. The second part has a lower thermal conductivity than the first part and is arranged adjacently to the first part. A first conductive film is formed on the first part and a second conductive film is formed on the second part. At least part of a gap is located above a boundary between the first part and the second part.
Claims18
An electron-emitting device comprising a first conductive film and a second conductive film that are arranged on a base body with a gap between them and in which an electric potential of the second conductive film is made higher than an electric potential of the first conductive film to emit an electron,
- wherein the base body includes a first part and a second part, the second part having a lower thermal conductivity than the first part and being arranged adjacently to the first part;
- wherein the first conductive film is formed on the first part and the second conductive film is formed on the second part;
- and
- wherein at least part of the gap is located over both the first part and the second part.
An electron-emitting device comprising a first conductive film and a second conductive film that are arranged separately from each other on a base body and in which an electric potential of the second conductive film is made higher than an electric potential of the first conductive film to emit an electron,
- wherein the base body includes a first part and a second part, the second part having a lower thermal conductivity than the first part and being arranged adjacently to the first part;
- wherein the first conductive film is formed on the first part and the second conductive film is formed on the second part;
- and
- wherein at least part of a boundary between the first part and the second part is located between the first conductive film and the second conductive film, under a gap over both the first part and the second part.
